Sounds like you have a very responsible and mature S20!!! This is an emotional time for you, no doubt.
I get the feeling that your h grew up in a home where it was not okay to show/express true feelings, that he had to hide them away.
Tell me if I am way off here but I think maybe that is why he gets on you at times.
